Ontologies, schemas & standards · across every domain
A curated, automatically evaluated catalog of ontologies, schemas, vocabularies and data standards across the sciences, from biomedicine and earth science to chemistry, engineering and the humanities. Every entry is scored against the FAIR principles, ontology quality, maintenance and community adoption, with the exact version evaluated and full provenance.
Cross-domain fit
Each line joins two domains that share ontologies or schemas, either because one resource is used in both, or because a resource in one imports a resource in the other. Thicker lines mean more sharing. Foundational ontologies, units and metadata vocabularies are the bridges.
A cross-species anatomy ontology covering animals, with extensive coverage of nervous system structures. It is the common anatomy backbone for many cell, expression and phenotype resources.
The reference ontology of cell types across organisms, with a large and growing branch of neuron and glial types.
A unified disease ontology that merges many disease resources, with comprehensive coverage of neurological and neurodevelopmental disorders.
The Ontology for Biomedical Investigations (OBI) project is developing an integrated ontology for the description of biological and clinical investigations. The ontology will represent the design of an investigation, the protocols and instrumentation used, the material used, the data generated and the type analysis performed on it. Currently OBI is being built under the Basic Formal Ontology (BFO).
Describes gene product functions, processes and locations, including synaptic transmission, neurotransmitter release and neuron development.
The Disease Ontology has been developed as a standardized ontology for human disease with the purpose of providing the biomedical community with consistent, reusable and sustainable descriptions of human disease terms, phenotype characteristics and related medical vocabulary disease concepts.
The System Package Data Exchange™ (SPDX®) specification is an open standard designed to represent systems containing software components as Software Bill of Materials (SBOMs). Additionally, SPDX supports AI, data, and security references, making it suitable for a wide range of risk management use cases. This _spdx3_ prefix is for SPDX 3.x versions. For earlier versions, use _spdx.term_.
The Proteomics Standards Initiative modification ontology (PSI-MOD) aims to define a concensus nomenclature and ontology reconciling, in a hierarchical representation, the complementary descriptions of residue modifications.
The controlled vocabulary of the CF metadata conventions, giving precise names, units and descriptions for climate, ocean and atmosphere variables in netCDF data.
Voc4Cat is a [SKOS](https://www.w3.org/TR/2009/REC-skos-reference-20090818/) vocabulary for the catalysis disciplines. The vocabulary was created in the [NFDI4Cat](http://www.nfdi4cat.org/) initiative. The first collection of terms was published in June 2023 with a focus on photo catalysis. Our goal is to continuously extend the vocabulary to other areas of catalysis and related disciplines like chemical engineering or materials science.
A domain ontology on food and bioproduct processing and characterization that is a specialization of the PO2 ontology (Process and Observation Ontology).
A community specification for packaging research data with their metadata, using schema.org in JSON-LD, so datasets, software and workflows can be shared with their context.
Submit it through GitHub. Every addition is reviewed, validated and evaluated automatically before it is merged.
